.6 Claims.

screen and storm door window having a window pane of flexible transparent or substantially transparent material which may consist of a single sheet of cellulose acetate or like plastic fastened at the marginal edges only, thereby rendering the door or window devoid of mullions or like intermediate framework.

Another object is to provide astorm door or window particularly adapted for window panes of the flexible type.

A further object is to provide a structure of the kind specified embody a flexible transparent pane which may be readily removed or applied whenever desired or when conditions warrant, as for example, to provide a screen door or window in summer and a storm door or window in winter.

A still further object of the invention is to generally improve and at the same time simplify combination screen and storm doors or windows for building structures.

The foregoing and other objects and advantages will become apparent in view of the following description taken in conjunction with the drawings, wherein:

Figure 1 is a view in front elevation of a combination screen and storm window in accordance with the invention;

Fig. 3, a section on the line 3-4, Fig. 2;

Fig. 4, a perspective of a slightly modified type of Window with respect to that shown in Figs. 1, 2 and 3;

Fig. 5, an enlarged detail in perspective of the upper right-hand corner portion of Fig. 4;

Fig. 6, a perspective of a storm door constructed in accordance with the invention;

Fig. 7, a similar view showing the window panel removed from the door of Fig. 6;

Fig. 8, a fragmentary-horizontal section illustrating the door of Fig. 8 installed in conjunction with an outside door;

Fig. 9, a view similar to the Fig. 8 showing a slight mpdification in structure;

Fig. 10, a further fragmentary section illustrating a storm window of the sliding type installed in conjunction with a regular window; and

Fig. 11, a fragmentary perspective view of a storm window or door illustrating a pane section made up of a transparent plastic sheet and screening in coacting reinforcing relation.

In carrying out the invention, I utilize a pane section of flexible transparent material suchas cellulose acetate, or one of the clear substantially transparent plastics capable of being fabricated in the form of sheets and which are generally made up in sizes according to specifications, or in rolls to be cut to length. This pane section is mounted in conjunction with a window or door screen by means of framework which holds the pane taut while at the same time permitting .the pane to be removed and replaced whenever it is desired or conditions warrant.

Referring to the drawings in detail, in Figs. 1, 2, and 3, a storm window is illustrated as being mounted within a casement made up of vertical side members l0, ill, a top rail H and a bottom member or sill I l. The storm window comprises vertical side rails or frames I 2 and I2 and top and bottom rails or frames II and i3 which are provided with suitable interlocking or mortised joint at their corners so that the said frame members may be connected in rigid or substantially rigid relation.

The outer side of the window has applied thereto screening M which is secured in place by means of suitable molding I5. The inner side of the window has applied thereover pane section l6 which is comprised of a sheet of clear transparent or substantially transparent plastic. In practice, I have used cellulose acetate material which may be purchased in the open market in continuous length rolls to be cut to size, or sheets of the required dimensions. The flexible transparent pane thus provided is connected to the window by means of molding strips It will be noted that the flexible tranlp 'e t pane section in the arrangement shown in Figs. 1,2and3isontheinnersideofthewindow. In this manner, the pane is readily accessible for removal to facilitate washing or cleaning from the interior of the dwelling or building to which the storm window may be applied. Furthermore, the screen protects the plastic sheet, rendering the latter less susceptible to damage or puncture. An intermediate molding strip 2| may be applied across the center of the frame to reinforce the sheet I at this point.

In Fig. 2, the flexible transparent pane section is shown partially removed in dotted line.

To prevent clouding of the pane section or sheet 16 due to trapped air and moisture, or to ventilate the room or compartment of the build-.- ing, an opening 22 is preferably formed in one of the frame members, for example in the bottom frame l3, and has thereover a closure slide 22, the latter being adjustable to regulate the amount of ventilation or to afford sufficient circulation of air within the dead air space between the inner and outer windows to prevent clouding thereof.

The storm window of Figs. 1, 2 and 3 may be mounted in any suitable manner within the main window frame or casement. In the present instance, the upper frame member l3 is provided with hangers 23 adapted to engage in brackets 23.

The type of storm window just described is of relatively simple construction yet at the same time it is unusually light and strong. The transparent pane or pane section It being flexible, is less liable to breakage than were window glass used and at the same time it may be more readily applied and removed without danger of damage or breakage. Furthermore, the plastic sheet is light in weightso that it considerably reduces the weight of the entire window structure. Actual use has demonstrated that a storm window of this type is a marked advance over those utilizing glass or like rigid materials susceptible of breakage. These flexible pane sections i6 are also of considerable advantage in case the storm windows are stored during the summer months, since the sheets may be rolled or laid flat in compact form without danger of breakage.

Figs. 4 and illustrate a storm window of the sliding typ In this instance, the window is made up of side frames or rails 24, 24 and top and bottom rails 25, 25, the side rails being formed with grooves 28 whereby the window may he slid into place in a suitable frame structure provided therefor. The outer side of the window has applied thereover a screen 21 by means of suitable molding strips 28; while on the inner side thereof is a flexible transparent sheet of plastic providing a pane section 29 secured in place by means of side molding strips 30, 30' and top and bottom strips 3|, ii. The top and bottom strips provide slideways or grooves 22, whereby the pane section 29 may be slid laterally in place or removed simply by removing the side strip 24, note the dotted line position in Fig. 4. In this instance, the side molding strip 30' is permanently connected to the adjacent edge of the pane section 29 to provide a finger piece and to hold the side section against distortion.

Figs. 6, 7 and 8 illustrate a storm door made up of side frames or rails 33, 33', a top rail 34, a bottom rail 34' and a bottom panel 25. The outer side of the door has applied thereover screening 36 by means of molding strips 21, while the inner side has applied thereover a flexible transparent sheet providing a pane or pane section 20, the latter being held in place by means of side molding strips 32, 8|, 9. top strip 4| and a bottom strip II. In this instance, the top and bottom strips may be provided with slideways or grooves with one of the side strips removable and connected to the flexible pane section a so that the latter may be slid in place and removed in the same manner as heretofore described in connection with Figs. 1 to 3, inclusive. The storm window thus provided may be hung by means of hooks ll and hanger brackets I.

Fig. 8 illustrates the storm door of Figs. 6 and 7 mounted in a door opening, the latter being deflned by an outer frame 42 and the door being hinged to said frame at 42. The usual outside door is generally indicated at H and is provided with a window section of glass or other suitable material as indicated at 44'. It will be noted that the plastic sheet or pane section 38 is made of one piece so that the use of mullions is rendered unnecessary.

Fig. 9 illustrates a slightly modifled form of storm door with respect to that shown in Figs. 6, '7, and 8. In this instance, parts are given similar reference characters except that an exponent a has been added. The difference in this instance is that the transparent pane section 30 38a is located exteriorly of the door, or on the exterior surface of the latter, with the screen in between the flexible pane and the usual or conventional window ll.

In Fig. 10, a storm window of the sliding type .5 is shown in conjunction with a conventional window. The outer frame or casement is indicated at 45 and is provided with windowretaining strips 46, 46' and runners 41. The storm window consists of a frame 48 mounted so on the runners 41 and having connected to the outer side thereof a flexible transparent pane section 49 by means of molding strip 50, and to the inner side a wire screen or screening 5| by means of molding 52. A window of the conventional type is indicated at 53 and is mounted between the strips 46, 46'.

Fig. 11 illustrates a structure wherein the pane section is made up of a plastic sheet and screening arranged in contiguous or face to face relation in order that one reinforces the other. In this instance the outer frame structure is generally indicated at 54, the transparent pane section or sheet at 55 and the screening at 55'. The flexible pane section may be mounted by means of suitable molding strips 56. This type of window or door panel may be used as a permanent pane section, or it may be removably mounted as heretofore described.

Actual use has demonstrated that this type of storm window or door may be manufactured at an unusually low cost while -at the same time the degree of transparency or visibility remains substantially that of the conventional window pane made of glass or like rigid material.

It will be understood that certain limited changes in construction and design may be made without departing from the spirit or scope of the invention as defined by the appended claims.
